The coin conveying device includes: a rail portion configured to form a conveyance path to convey a coin; a conveying portion including holders connected endlessly, each holder being configured to hold one coin, the conveying portion being configured to convey the input coin from below to above by displacing the conveying portion in one direction along the rail portion; and a controller configured to, when the input coin is put in the conveying portion, displace the conveying portion in a reverse direction that is opposite to the one direction for a predetermined time, and displace the conveying portion in the one direction after the predetermined time has elapsed.
The above and other objects, features, advantages and technical and industrial significance of this disclosure will be better understood by reading the following detailed description of presently preferred embodiments of the disclosure, when considered in connection with the accompanying drawings.
An exemplary embodiment of a coin conveying device according to the disclosure is explained in detail below referring to the accompanying drawings.
A coin processing apparatus 1 described as an example herein is, for example, applied as a change machine, and stores input coins according to the denomination, and dispenses a stored coin under a dispensing instruction. The coin processing apparatus 1 includes a coin verification device 10a and a coin conveying device 10b.
Coin Verification Device
The coin verification device 10a discriminates the genuineness and the denomination of a coin that is put therein through a coin insertion unit 2. The coin insertion unit 2 has a coin insertion slot 2a, and is a portion from which a coin is input.
The coin verification device 10a includes, as shown in
The conveying pulley 21 is, as shown in
The conveying pulley 21a on the rear side described above is a driving pulley that rotates about a center axis of itself with by a driving force of the coin-verification conveying motor 21c. The conveying pulley 21a on the rear side rotates counterclockwise when viewed from a left side, with the driving force given by the coin-verification conveying motor 21c.
The conveying belts 22 are arranged in a left-and-right pair, and are endlessly put between the respective conveying pullies 21 under tension. The conveying belt 22 is displaced in an extending direction thereof, with rotation of the conveying pulley 21a by the driving force of the coin-verification conveying motor 21c. More specifically, the conveying belt 22 is displaced in such a manner that an upper portion moves toward a rear side and a lower portion moves toward a forward side with rotation of the conveying pulley 21a on the rear side.
A conveying pulley 21b on the front side that is linked to the conveying pulley 21a on the rear side through the conveying belt 22 rotates about a center axis of itself with the rotation of the conveying pulley 21a on the rear side in the counterclockwise direction when viewed from the left. That is, the conveying pulley 21b is a driven pulley that is rotated according to the rotation of the conveying pulley 21a on the rear side.
There are a plurality of the push conveying members 23 arranged such that each of the members 23 is arranged astride a left and right pair of the conveying belts 22 at regular intervals along the extending direction of the conveying belts 22. As shown in
In the push conveying member 23, a surface 23c that faces toward a downstream side in the direction of displacement of the conveying belt 22, that is a surface facing rearward at a portion above the conveying belt 22 and facing frontward at a portion below the conveying belt 22, is formed in a V-shape. That is, the push conveying member 23 forms a V-shape on the surface 23c that faces toward the downstream side in the direction of displacement of the conveying belt 22, as shown in
The output flapper 24 is arranged at a conveyance base portion 26 that is arranged between a left and right pair of the conveying belts 22 as shown in
The output flapper 24 is closed normally so as to suppress passage of coins through the outlet 24a. As an output-flapper driving mechanism 24b drives, the output flapper 24 swings in an opening direction to open the outlet 24a. The output-flapper driving mechanism 24b drives to cause the output flapper 24 to swing in the opening direction when a drive command is given by the coin-verification control unit 60, and stops driving when a drive stop command is given by the coin-verification control unit 60 to cause the output flapper 24 to close the outlet 24a.
The counterfeit coin outlet 25 is a rectangular-shaped opening that is formed on the rear side of the outlet 24a at the conveyance base portion 26 as shown in
The guide member 30 is arranged at the top portion 20a2 of the conveying-device main unit 20a at a portion above the outlet 24a as shown in
The guide axis 31 is a cylindrical member that extends along the left and right direction. The guide action unit 32 is a member that extends outward in a direction of diameter of the guide axis 31, more specifically, toward the rear side.
The guide member 30 is arranged swingably about a center axis of the guide axis 31 by such an arrangement that the guide axis 31 is set at a guide support piece 20a4 arranged at the top portion 20a2 in such a manner that the guide action unit 32 passes through a guide opening 20a3 formed at the top portion 20a2.
More specifically, the guide member 30 is arranged swingably such that a lower end portion of the guide action unit 32 moves back and forth in a passage region A of coins that is conveyed toward the rear side by the verified-coin conveying unit 20, and is normally in a state in which the lower end portion of the guide action unit 32 has entered the passage region A. The guide member 30 allows, when the outlet 24a is open by the output flapper 24, a coin to pass toward the rear side by making a swinging movement of receding from the passage region A by being pushed by the coin passing through the passage region A, and abuts on a coin passing through the passage region A, on the other hand, when the outlet 24a is opened by the output flapper 24, to guide the coin to the outlet 24a abutting on the coin passing through the passage region A.
The verified-coin separating unit 40 sends coins input through the coin insertion unit 2 to the verified-coin conveying unit 20, separating to each coin.
The separator main unit 41 includes a rotator housing unit 41a in a cylindrical shape with a bottom, and a feeding opening 41b through which a coin is fed to the verified-coin conveying unit 20, and a driving-force giving opening 41c to give a rotation driving force to the rotator 42 are formed therein. On a bottom surface portion 41a1 of the rotator housing unit 41a in this separator main unit 41, multiple guiding protrusions 41a2 to guide a coin to the feeding opening 41b are formed to protrude upward as shown in
The rotator 42 has a substantially a disc shape, and is housed in the rotator housing unit 41a of the separator main unit 41 rotatably about a center axis of itself. In the rotator 42, multiple coin passage holes 42a (four holes in the illustrated example) are formed on the same circumference about the center axis.
On a side surface of the rotator 42, a gear 44a of a driving-force transfer unit 44 is engaged therewith through the driving-force giving opening 41c described above. The driving-force transfer unit 44 is present between the conveying pulley 21b on the front side and the rotator 42 as shown in
As described above, as the conveying pulley 21b on the front side is a driven pulley that is rotated according to rotation of the conveying pulley 21a on the rear side, the rotation driving force of the rotator 42 is given by the coin-verification conveying motor 21c. That is, the rotation of the rotator 42 and the rotation of the conveying pulley 21 are given by a common driving source, and displacement of the rotator 42 and the conveying belt 22 are synchronized.
The separator cover 43 is arranged to cover the rotator housing unit 41a of the separator main unit 41. In this separator cover 43, an inlet 54a and a movable flapper 45. An inlet 43a is an opening to put a coin input at the coin insertion unit 2 into the rotator 42 in the rotator housing unit 41a.
The movable flapper 45 has a movable axis unit 45a and a movable action unit 45b as shown in
The movable flapper 45 is arranged swingably about a center axis of the movable axis unit 45a by such an arrangement that the movable axis unit 45a is set at a movable support piece 43b arranged at the separator cover 43 in such a manner that the movable action unit 45b passes through the inlet 43a. More specifically, the movable flapper 45 is swingably arranged in such a manner that a part of an end portion of the movable action unit 45b is in contact with an upper surface of the rotator 42 as shown in
The discriminating unit 50 is arranged at a position that is on the rear side from the verified-coin separating unit 40, and is on the front side from the outlet 24a as shown in
The coin-verification control unit 60 is to perform overall control of the operation of the coin verification device 10a according to a program and data stored in a memory 61. The coin-verification control unit 60 can be implemented by causing a processing device such as a central processing unit, to execute a program, that is, by software, or can be implemented by hardware such as an integrated circuit (IC), or can be implemented by combining software and hardware.
In the coin verification device 10a configured as above, when multiple coins are input through the coin insertion unit 2 and an operation command is given by a coin-processor main-control unit 200 that performs overall control of operation of the coin processing apparatus 1 to the coin-verification control unit 60, the coin-verification control unit 60 gives a drive command to the coin-verification conveying motor 21c.
Thus, the coin-verification conveying motor 21c is activated, and in the verified-coin conveying unit 20, the conveying pulley 21 rotates in a counterclockwise direction viewed from the left to displace the conveying belt 22 along the extending direction. Moreover, with the rotation of the conveying pulley 21, the rotator 42 of the verified-coin separating unit 40 rotates through the driving-force transfer unit 44 in a clockwise direction viewed from the above.
When coins input from the coin insertion unit 2 are brought to the upper surface of the rotator 42 through the inlet 43a of the separator cover 43, the verified-coin separating unit 40 guides these coins to the respective coin passage holes 42a in a laid-down state. As described above, as the movable flapper 45 is swingably arranged in a state in which a part at the end portion of the movable action unit 45b is in contact with the upper surface of the rotator 42 at the separator cover 43, the movable action unit 45b of the movable flapper 45 presses the coins on the upper surface of the rotator 42 to guide the coins to the coin passage holes 42a in the laid-down state. Thus, the coins guided to the coin passage holes 42a are stacked in the coin passage holes 42a.
Out of the coins guided into the coin passage holes 42a and stacked therein, a coin at the bottom slides on the bottom surface portion 41a1 of the rotator housing unit 41a in the separator main unit 41 by the rotation of the rotator 42. As the guiding protrusions 41a2 are formed on the bottom surface portion 41a1 of the rotator housing unit 41a, as shown in
The coin provided to the verified-coin conveying unit 20 through the feeding opening 41b is placed in a laid-down state on a top surface of the conveyance base portion 26. As described above, because the conveying belts 22 are displaced in the extending direction, the push conveying members 23 fixed to the conveying belts 22 press the coin placed on the top surface of the conveyance base portion 26 toward the rear side, thereby conveying the coin toward the rear side.
The push conveying member 23 has the surface 23c that faces the downstream side in the direction of displacement of the conveying belt 22 and is formed in a V-shape, and therefore, as shown in
When the conveyed coin reaches the discrimination area of the discriminating unit 50 by thus being conveyed toward the rear side pushed by the push conveying members 23, the discriminating unit 50 discriminates the authenticity and denominations of the coin. This discriminating unit 50 sends a discrimination result to the coin-verification control unit 60 as a discrimination signal.
The coin-verification control unit 60 receives the discrimination signal from the discriminating unit 50, and gives a drive command to the output-flapper driving mechanism 24b when the discrimination result indicates a genuine coin. Thus, the output-flapper driving mechanism 24b starts driving, and the output flapper 24 slides in the opening direction to open the outlet 24a. When the output flapper 24 thus opens the outlet 24a, the coin being conveyed toward the rear side pressed by the push conveying members 23 passes through the outlet 24a while touching the guide member 30 and changing the posture, to be output to the coin conveying device 10b. After the coin discriminated as a genuine coin passes through the outlet 24a, the coin-verification control unit 60 gives a drive stop command to the output-flapper driving mechanism 24b. Thus, the outlet 24a is closed by the output flapper 24.
On the other hand, when the coin-verification control unit 60 receives the discrimination signal from the discriminating unit 50 and the discrimination result indicates a counterfeit coin, the coin-verification control unit 60 maintains a closed state of the outlet 24a with the output flapper 24 without giving a drive command to the output-flapper driving mechanism 24b.
The coin that has passed the discrimination area in a state of being pushed by the push conveying members 23 and conveyed to the rear side passes the upper surface of the output flapper 24, and passes through the counterfeit coin outlet 25 to be dropped downward. The coin thus dropped downward is placed at a bottom portion of the conveying-device main unit 20a in a laid-down state.
The downward portions of the conveying belts 22 are displaced toward the front side by rotation of the conveying pulley 21. Therefore, at the downward portion of the verified-coin conveying unit 20, as shown in
Thus, the verified-coin conveying unit 20 sends a coin (counterfeit coin) conveyed toward the front side to an ejection unit 3 (refer to
The ejection unit 3 is structured such that an ejection belt 3b is endlessly arranged by being hooked between a left and right pair of ejection pulleys 3a under tension. This ejection unit 3 sends a coin ejected thereby by rotation of the ejection pulley 3a on a right side by a driving force of the ejection motor 3c to a payout unit 4, to cause to eject the coin from a coin ejection outlet 4a(refer to
As explained above, the coin verification device 10a discriminates the authenticity and denominations of coins input through the coin insertion unit 2, and sends a coin that is discriminated as a genuine coin to the coin conveying device 10b, and ejects a coin that is discriminated as a counterfeit coin to outside through the payout unit 4.
According to the coin verification device 10a, verified-coin conveying unit 20 conveys a coin that has been conveyed toward the rear side and has been discriminated as a counterfeit coin by the discriminating unit 50 is conveyed toward the front side after passing through the counterfeit coin outlet 25, and therefore, a length in a front-rear direction of the verified-coin conveying unit 20 can be shortened, thereby enabling to downsize the coin processing apparatus 1.
According to the coin verification device 10a, in the push conveying member 23 constituting the verified-coin conveying unit 20, as the surface 23c that pushes a coin as the conveying belts 22 are displaced is formed in a V shape, a coin can be conveyed in a state brought to a central part in a left and right direction, and thus, coins can be conveyed stably, controlling a conveyance position of a coin, and the accuracy of discrimination performed by the discriminating unit 50 can be improved.
Con Conveying Device
The coin conveying device 10b exemplified herein conveys coins for which authenticity and denominations have been discriminated by the coin verification device 10a, and determines the denominations of the coins while conveying, and sends the coins to a coin storage unit 5 (refer to
The coin conveying device 10b includes a rail portion 70, a conveying portion 80, a reverse roller 90, a control unit 100 (refer to
The rail portion 70 includes a first rail-forming member 71, a second rail-forming member 72, a third rail-forming member 73, and a fourth rail-forming member 74 as shown in
The first rail-forming member 71 forms a conveyance path HK at a rear right part of the coin conveying device 10b. This first rail-forming member 71 has a curved lower extension 71a that curves downward so as to protrude toward the rear side. That is, the first rail-forming member 71 structures a falling part that extends in a state curved downward.
The second rail-forming member 72 forms the conveyance path HK at a lower part of the coin conveying device 10b. This second rail-forming member 72 has a first left extension 72a, a front extension 72b, and a first right extension 72c.
The first left extension 72a is a portion that is connected to the curved lower extension 71a in the first rail-forming member 71, and that extends leftward. The front extension 72b is a portion that extends frontward from an end of extension of the first left extension 72a. The first right extension 72c is a portion that extends rightward from an end of extension of the front extension 72b. In the second rail-forming member 72, a slot 72d to which a coin discriminated as a genuine coin by the coin verification device 10a is put in is formed.
The third rail-forming member 73 forms the conveyance path HK at a front right part of the coin conveying device 10b. This third rail-forming member 73 is connected to the first right extension 72c of the second rail-forming member 72, and has a curved upper extension 73a that curves upward so as to protrude toward the rear side. That is, the third rail-forming member 73 structures a rising part that extends in a state curved upward.
The fourth rail-forming member 74 forms an upper part of the conveyance path HK of the coin conveying device 10b. This fourth rail-forming member 74 has a second left extension 74a, a rear extension 74b, and a second right extension 74c.
The second left extension 74a is a portion that extends leftward. This second left extension 74a is curved in such a manner that a right end portion 74a1 faces an upper end portion 73a1 of the curved upper extension 73a of the third rail-forming member 73. The rear extension 74b is a portion that extends toward the rear side from an end of extension of the second left extension 74a. The second right extension 74c is a portion that extends rightward from an end of extension of the rear extension 74b. This second right extension 74c is curved in such a manner that a right end portion 74c1 faces an upper end portion 71a1 of the curved lower extension 71a of the first rail-forming member 71.
As described, the rail portion 70 structures the endless conveyance path HK with the first rail-forming member 71, the second rail-forming member 72, the third rail-forming member 73, and the fourth rail-forming member 74 connected sequentially.
Moreover, in the above rail portion 70, the fourth rail-forming member 74 is inserted through a first support hole 76a (refer to
The conveying portion 80 is engaged with a driving conveyance pulley 85a and plural driven conveyance pulleys 85b (three in the illustrated example) at some parts thereof, and is displaced along the conveyance path HK as the conveying portion 80 is rotated by a driving force of a conveyance driving motor 86.
The conveyance driving motor 86 is activated when a drive command is given by the conveyance control unit 140 and is capable of driving in forward and reverse rotation. When the conveyance driving motor 86 drives in a forward rotation direction, the respective holders 81 of the conveying portion 80 are displaced relative to rail portion 70 to move in one direction in order of the first rail-forming member 71, the second rail-forming member 72, the third rail-forming member 73, and the fourth rail-forming member 74.
On the other hand, when the conveyance driving motor 86 drives in a reverse rotation direction, the respective holders 81 of the conveying portion 80 are displaced relative to the rail portion 70 to move in the opposite direction in order of the fourth rail-forming member 74, the third rail-forming member 73, the second rail-forming member 72, and the first rail-forming member 71.
In the conveying portion 80, due to the shape of the conveyance path HK, a posture of the holder 81 when passing through the second rail-forming member 72 and a posture of the holder 81 when passing through the fourth rail-forming member 74 are oriented vertically inverted.
The holder 81, which is a component of the conveying portion 80 described above, holds one coin each, and is structured with a holder pushing member 82 and a holder control member 83 connected by a holder connecting member 84.
The holder pushing member 82 is a stick-shaped body that extends from the inside toward the outside of the conveyance path HK. This holder pushing member 82 pushes a coin to the downstream side of the conveyance path HK as the conveying portion 80 is displaced, and is structured such that a pushing surface 82a facing the downstream side of the conveyance path HK is inclined gradually toward the upstream side from the inside to the outside.
Moreover, as shown in
The holder control member 83 has a shape similar to the holder pushing member 82, and is a stick-shaped body that extends from the inside toward the outside of the conveyance path HK. This holder control member 83 is connected to the holder pushing member 82 at an inside thereof through the holder connecting member 84, and controls a position of a coin pushed by the holder pushing member 82 not to be apart from the holder pushing member 82 more than necessary. The holder control member 83 is connected, at the inside thereof, to the holder pushing member 82 that constitutes the holder 81 positioned on the downstream side of this holder 81.
The holder control member 83 is structured such that a downstream surface 83a facing the downstream side of the conveyance path HK is inclined gradually toward the upstream side from the inside to the outside. This holder control member 83 has a third concave portion 83b that allows the rail convex portion 71A formed in the first rail-forming member 71, the rail convex portion 72A formed in the second rail-forming member 72, and the rail convex portion 73A formed in the third rail-forming member 73 to enter, and a fourth concave portion 83c that allows the rail convex portion 74A formed in the fourth rail-forming member 74 to enter. On the downstream surface 83a at a bottom portion of the third concave portion 83b, an inclined surface 83d is formed.
As described above, the upper end portion 73a1 of the curved upper extension 73a of the third rail-forming member 73 and the right end portion 74a1 of the second left extension 74a of the fourth rail-forming member 74 face each other. Therefore, as shown in
Furthermore, as described above, the upper end portion 71a1 of the curved lower extension 71a of the first rail-forming member 71 and the right end portion 74c1 of the second right extension 74c of the fourth rail-forming member 74 face each other. Therefore, although not explicitly shown in the drawings, when passing through the facing portion, the holder 81 is in a state in which the rail convex portion 71A of the first rail-forming member 71 enters the first concave portion 82b of the holder pushing member 82, and the rail convex portion 74A of the fourth rail-forming member 74 enters the second concave portion 82c of the holder pushing member 82, and similarly, in a state in which the rail convex portion 71A of the first rail-forming member 71 enters the third concave portion 83b of the holder control member 83, and the rail convex portion 74A of the fourth rail-forming member 74 enters the fourth concave portion 83c of the holder control member 83.
The reverse roller 90 is rotatably provided to the first support plate 76 so as to face the third rail-forming member 73. This reverse roller 90 is linked to the conveyance driving motor 86 through a conveyance linkage unit 91, and rotates about an axis of itself by a driving force of the conveyance driving motor 86.
The control unit 100 includes a posture control member 101 and a passage control member 102. The posture control member 101 is attached to a posture-control supporting unit 103 mounted on the first support plate 76 so as to face the third rail-forming member 73 in an area above the reverse roller 90 as shown in
The posture control member 101 controls the posture of a coin that is conveyed upward at the curved upper extension 73a of the third rail-forming member 73 by pushing the coin toward the third rail-forming member 73 (rail portion 70).
The passage control member 102 is arranged at the second support plate 77 so as to face a part at which the curved lower extension 71a of the first rail-forming member 71 and the first left extension 72a of the second rail-forming member 72 are connected to each other as shown in
The passage control axis 102a is a cylindrical member that extends along the front and rear direction, and is swingably supported about a center axis of the passage control axis 102a by the second support plate 77 at both end portions. Two pieces of the passage-control acting portions 102b are provided in a front-and-rear pair, and are positioned in a state separated from each other, and extends from a center region portion of the passage control axis 102a outward in a direction of diameter of the passage control axis 102a.
The passage control member 102 is pushed rightward by a passage control spring 102c, which is a pushing means, and an end portion of the passage-control acting portion 102b has entered a passage area B of a conveyed coin.
As shown in
On the other hand, when the conveying portion 80 is displaced in a reverse direction by the conveyance driving motor 86 driving in the reverse rotation direction, the passage control member 102 separate the coin that is being conveyed in the reverse direction by the conveying portion 80 in the second rail-forming member 72 from the holder 81 to prevent the coin from passing through the curved lower extension 71a of the first rail-forming member 71 as shown in
The determining unit 110 is provided at the fourth rail-forming member 74. This determining unit 110 determines denominations of coins that are conveyed pushed by the holder pushing member 82 of the holder 81 in a predetermined determination area in the fourth rail-forming member 74. A determination result by the determining unit 110 is output to the conveyance control unit 140 as a determination signal.
The returning unit 120 is arranged on a downstream side to the determining unit 110 (determination area) in the conveyance path HK that is formed by the fourth rail-forming member 74, and includes a return opening 121 and a return gate 122.
The return opening 121 is an opening in size that allows passage of coins of all kinds of denominations conveyed by the conveying portion 80, and is communicated to the payout unit 4.
The return gate 122 closes the return opening 121 in a normal state, but opens the return opening 121 by swinging when a return command is given.
The separating unit 130 is arranged on a downstream side to the returning unit 120 in the conveyance path HK that is formed by the fourth rail-forming member 74. This separating unit 130 includes multiple separation passages 131 and separation gates 132.
The multiple separation passages 131 are openings each of which has a sufficient size to let a coin pass. The separation gates 132 correspond to the respective separation passages 131, and are arranged across the conveyance path HK that is formed by the fourth rail-forming member 74. More specifically, the separation gate 132 is structured with multiple separation-gate action pieces 132b attached at an end portion of a separation gate axis 132a in a long cylindrical shape, and is supported rotatably about a center axis of the separation gate axis 132a.
With a base portion of the separation gate axis 132a, as shown in
On the other hand, when a drive command is given from the conveyance control unit 140 and the separation drive solenoid 135 is energized, the plunger 133 is drawn in by the separation drive solenoid 135, and rotates the separation gate 132 about the center axis of the separation gate axis 132a as shown in
When the separation-gate action pieces 132b thus enter the conveyance path HK, an inclined portion K that is inclined toward the downstream side in the conveyance direction from an end portion of the separation-gate action pieces 132b toward the separation passage 131 is formed as shown in
The conveyance control unit 140 performs overall control of operation of the coin conveying device 10b according to a program and data stored in a memory 141. The conveyance control unit 140 can be implemented by, for example, causing a processing device such as a central processing unit (CPU) to execute a program, that is, by software, can be implemented by hardware such as an integrated circuit (IC), or can be implemented by combining software and hardware.
Moreover, as described above, the conveyance control unit 140 gives a drive command to the conveyance driving motor 86 to make it drive in the forward rotation direction or the reverse rotation direction, and when making the conveyance driving motor 86 to drive in the forward rotation direction, the conveyance control unit 140 performs pulse width modulation (PWM) control to approximate a predetermined conveying force.
On the other hand, when making the conveyance driving motor 86 to drive in the reverse rotation direction, the conveyance control unit 140 controls to a conveying force larger than the conveying force in the case of driving in the forward rotation direction.
That is, the conveyance control unit 140 displaces the conveying portion 80 in such a manner that a driving force for displacement in one direction is smaller than a driving force for displacement in a reverse direction.
The coin conveying device 10b having the configuration as described above operates as follows when a coin that has been discriminated as a genuine coin is output from the coin verification device 10a and a drive command is given by the coin-processor main-control unit 200 to the conveyance control unit 140.
Specifically, the conveyance control unit 140 gives a drive command for the reverse direction to the conveyance driving motor 86 to make the conveyance driving motor 86 drive in the reverse direction, and causes the conveying portion 80 to displace in the reverse direction for predetermined time. Thus, the coin put into the second rail-forming member 72 from the slot 72d is conveyed in the reverse direction in the second rail-forming member 72 by the conveying portion 80.
As the passage control member 102 separates the coin, which is being conveyed in the reverse direction by the conveying portion 80, from the holder 81 to prevent the coin from passing through the curved lower extension 71a of the first rail-forming member 71, the coin put into the second rail-forming member 72 from the slot 72d can be accumulated in the second rail-forming member 72.
When the predetermined time passes, the conveyance control unit 140 gives a drive command for the forward direction to the conveyance driving motor 86 to make the conveyance driving motor 86 drive in the forward direction, and causes the conveying portion 80 to displace in one direction. Thus, the coin accumulated in the second rail-forming member 72 can be conveyed in one direction along the conveyance path HK.
The holder 81 of the conveying portion 80 has the inclined surface 82d formed on the pushing surface 82a at the bottom portion of the first concave portion 82b in the holder pushing member 82. Therefore, as the holder 81 is displaced in a state in which the rail convex portion 73A of the third rail-forming member 73 enters the first concave portion 82b when passing the curved upper extension 73a of the third rail-forming member 73, the inclined surface 82d is to be at a position separated from the rail.
Therefore, even when two pieces of coins overlapped with each other are being pushed by the holder pushing member 82 to be conveyed in an area below the reverse roller 90, as shown in
Furthermore, in an area above the reverse roller 90, as the posture control member 101 pushes a coin that is being conveyed upward at the curved upper extension 73a of the third rail-forming member 73 against the third rail-forming member 73 (rail portion 70) and thereby controls the posture of the coin, it is possible to avoid the coin from being derailed while passing the curved upper extension 73a.
Moreover, the upper end portion 73a1 of the curved upper extension 73a of the third rail-forming member 73 and the right end portion 74a1 of the second left extension 74a of the fourth rail-forming member 74 face each other, and when passing through the facing portion, the holder 81 is in a state in which the rail convex portion 73A of the third rail-forming member 73 enters the first concave portion 82b of the holder pushing member 82, and the rail convex portion 74A of the fourth rail-forming member 74 enters the second concave portion 82c of the holder pushing member 82. Therefore, a coin that is pushed by the holder pushing member 82 is conveyed also in a state of being sandwiched between the upper end portion 73a1 of the curved upper extension 73a and the right end portion 74a1 of the second left extension 74a, the coin is not likely to be derailed from the conveyance path HK.
As described, in the holder 81 passed through the third rail-forming member 73, one piece of coin is held. As the pushing surface 82a of the holder pushing member 82 that constitutes each of the holders 81 in the conveying portion 80 is structured in an inclined manner, it is possible to convey a coin stably, keeping it on an outer side in the conveyance path HK.
As described above, in the conveying portion 80, the posture of the holder 81 when passing through the second rail-forming member 72 and the posture of the holder 81 when passing through the fourth rail-forming member 74 are oriented vertically inverted. Therefore, when the holder 81 is displaced in a state in which the rail convex portion 74A of the fourth rail-forming member 74 enters the second concave portion 82c, as shown in
When the denomination of a coin that passes the determination area is determined by the determining unit 110, the conveyance control unit 140 gives a drive command to the corresponding separation drive solenoid 135 according to the determination result to energize the separation drive solenoid 135. As a result, the corresponding separate gate 132 is caused to rotate about the center axis of the separation gate axis 132a, to bring the separation-gate action pieces 132b into the conveyance path HK. The inclined portion K that is formed by the separation-gate action pieces 132b guides the coin to the corresponding separation passage 131, and thereby store the coin in the coin storage unit 5.
When the denomination of a coin is not determined by the determining unit 110, the conveyance control unit 140 does not give a drive command to any of the separation drive solenoids 135. In this case, all the separation gates 132 are in a state in which the separation-gate action pieces 132b are separated from the conveyance path HK. Therefore, the coin that has passed the fourth rail-forming member 74 proceeds straight to the first rail-forming member 71 and then to the second rail-forming member 72, and repeats the passage in the conveyance path HK described above, to be determined again by the determining unit 110.
When all of coins that have been conveyed in the conveyance path HK are thus stored in the coin storage unit 5 according to denominations within predetermined operation time, the conveyance control unit 140 gives a drive stop command to the conveyance driving motor 86 to stop driving of the conveyance driving motor 86, and thereafter, outputs a signal indicating that conveyance of the coins are completed to the coin-processor main-control unit 200.
On the other hand, when the above operation time has passed with a coin remaining in the conveyance path HK, the conveyance control unit 140 gives a return command to the return gate 122 to open the return opening 121, and guides the coin being conveyed in the conveyance path HK to the return opening 121 to output to the payout unit 4, and ejects the coin to the outside from the payout unit 4.
As explained above, according to the coin conveying device 10b, the conveying portion 80 that is structured with the holders 81 that can hold coins one by one and are endlessly connected is displaced in one direction along the rail portion 70 forming the predetermined conveyance path HK having the curved upper extension 73a (rising portion) that extends curving upward, and thereby conveys an input coin from below to above. Therefore, compared to a conventional manner of conveying coins with multiple belts that are arranged endlessly by being hooked to a pair of rollers under tension, an installation area of the coin processing apparatus 1 can be reduced, and thus, downsizing of the coin processing apparatus 1 is enabled.
In addition, the posture control member 101 controls the posture of a coin that is conveyed upward at the curved upper extension 73a of the third rail-forming member 73 by pushing the coin toward the third rail-forming member 73 (rail portion 70). Therefore, it is possible to prevent the coin from being derailed while passing the curved upper extension 73a, and thus suppress the occurrence of a coin jam during conveyance.
Furthermore, according to the coin conveying device 10b described above, when a coin is put into the conveying portion 80, the conveyance control unit 140 displaces the conveying portion 80 in the reverse direction for predetermined time, and then displaces the conveying portion 80 in one direction after the predetermined time passes. Therefore, a coin that is put in from the slot 72d can be accumulated in the second rail-forming member 72, and more coins can be accepted from the coin verification device 10a.
Moreover, according to the coin conveying device 10b described above, the conveyance control unit 140 displaces the conveying portion 80 such that a driving force for displacement in one direction is smaller than a driving force for displacement for the reverse direction. Therefore, if a problem occurs at the time of conveying a coin in one direction along the conveyance path HK and a coin jam is caused, by displacing the conveying portion 80 in the reverse direction by driving the conveyance driving motor 86 in the reverse direction, a larger power can be exerted for releasing the coin jam than that of the time when the coin gets clogged, and the coin jam can be resolved.
Furthermore, according to the coin conveying device 10b described above, the fourth rail-forming member 74 can swing in the vertical direction about the center axis of the first protrusion 75a and the second protrusion 75b. Therefore, when a coin jam occurs in the second rail-forming member 72 or the like, the coin causing the coin jam can be easily removed from the second rail-forming member 72 by swinging the fourth rail-forming member 74 upward.
As above, the exemplary embodiment of the disclosure has been explained, the disclosure is not limited thereto, and various modifications can be made.
The coin-verification control unit 60 and the conveyance control unit 140 are separately configured in the embodiment described above, but can be configured integrally with the coin-processor main-control unit 200 in the disclosure.
Although not specifically explained in the above embodiment, in the curved portion from the second left extension 74a to the rear extension 74b of the fourth rail-forming member 74 and in the curved portion from the rear extension 74b to the second right extension 74c, in the disclosure, the rail convex portion 74A is only required to be structured such that the protrusion height gradually decreases toward the outward direction. This enables to keep a coin passing therethrough to the outer side in the conveyance path HK.
Moreover, in the disclosure, a space to keep coins can be provided at a portion outside the curved portion from the first left extension 72a to the front extension 72b of the second rail-forming member 72 or the curved portion from the front extension 72b to the first right extension 72c.
According to the disclosure, a conveying portion that is structured with holders that can hold coins one by one and are connected endlessly is displaced in one direction along a rail portion forming a conveyance path to convey coins, and thereby conveys an input coin from below to above. Therefore, such an effect is obtained that compared to a conventional manner of conveying coins with multiple belts that are endlessly arranged by being hooked to a pair of rollers under tension, an installation area of a coin processing apparatus can be reduced, and thus, downsizing of the coin processing apparatus is enabled.
In addition, when an input coin is put into the conveying portion, a control unit causes the conveying portion to displace in a reverse direction opposite to one direction for predetermined time, and thereafter causes the conveying portion to displace in one direction after the predetermined time has elapsed. Therefore, such an effect is obtained that the input coin can be accumulated, and more coins can be accepted.
Although the disclosure has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
